## Detailed Description

Input/Output stream.

## Member Typedef Documentation

## ◆ fmtflags

typedef unsigned int ios_base::fmtflags
| inherited

type for format flags

## ◆ iostate

typedef unsigned char ios_base::iostate
| inherited

typedef for iostate bitmask

## ◆ off_type

typedef int32_t ios_base::off_type
| inherited

type for relative seek offset

## ◆ openmode

typedef uint8_t ios_base::openmode
| inherited

typedef for iostream open mode

## ◆ pos_type

typedef uint32_t ios_base::pos_type
| inherited

type for absolute seek position

## ◆ streamsize

typedef uint32_t ios_base::streamsize
| inherited

unsigned size that can represent maximum file size. (violates spec - should be signed)

## Member Enumeration Documentation

## ◆ seekdir

enum ios_base::seekdir
| inherited

enumerated type for the direction of relative seeks

Enumerator

## Member Function Documentation

## ◆ bad()

bool ios::bad | ( |  | ) | const
| inline inherited

Returns
  true if bad bit is set else false.

## ◆ clear()

void ios::clear | ( | iostate | state = `goodbit` | ) |

Clear iostate bits.

Parameters

  [in] | state | The flags you want to set after clearing all flags.

## ◆ eof()

bool ios::eof | ( |  | ) | const
| inline inherited

Returns
  true if end of file has been reached else false.

Warning: An empty file returns false before the first read.

Moral: eof() is only useful in combination with fail(), to find out whether EOF was the cause for failure

## ◆ fail()

| inline inherited

Returns
  true if any iostate bit other than eof are set else false.

## ◆ fill() [1/2]

| inline inherited

Set fill character

Parameters

  [in] | c | new fill character

Returns
  old fill character

| inline inherited

Returns
  format flags

## ◆ flags() [2/2]

fmtflags ios_base::flags | ( | fmtflags | fl | ) |
| inline inherited

set format flags

Parameters

  [in] | fl | new flag

Returns
  old flags

## ◆ flush()

ostream& ostream::flush | ( |  | ) |
| inline inherited

Flushes the buffer associated with this stream. The flush function calls the sync function of the associated file.

Returns
  A reference to the ostream object.

## ◆ gcount()

streamsize istream::gcount | ( |  | ) | const
| inline inherited

Returns
  The number of characters extracted by the last unformatted input function.

## ◆ get() [1/3]

int istream::get | ( |  | ) |
| inherited

Extract a character if one is available.

Returns
  The character or -1 if a failure occurs. A failure is indicated by the stream state.
